- Description

This bulletin provides information related to the Oil Control Valve (OCV) used in Constant Variable Valve Timing (CVVT). If at any time the OCV is suspected as a cause of rough idling, poor acceleration, camshaft timing misalignment-related trouble codes, misfire-related trouble codes, etc., on a Kia vehicle equipped with Continuously Variable Valve Timing (CVVT) system, be sure to perform the OCV inspection procedure below before replacement. If the OCV operates normally, inspect for other engine malfunctions. Do not replace the OCV.

→Replace the OCV.

2. Check if the OCV operates normally by providing 12V power supply as shown. Do not apply voltage for longer than 5 seconds at a time; Do not overheat OCV windings.

3. When 12V power is provided to the OCV, the OCV must move forward as shown in the right picture. A: Maximum retarded valve timing condition (12V not provided) Normally Open B: Maximum advanced valve timing condition (12V provided) Closed when energized.

4. If the OCV does not move forward, examine carefully for a foreign object like an aluminum chip or flashing which maybe jammed inside OCV passage. - Blow out the foreign object using compressed air, reuse the OCV and then verify that the fault is corrected. The OCV can be replaced for the following conditions: • Resistance out of specification • Valve does not move when voltage is applied • Foreign debris cannot be removed from the OCV
